Looking for something new in the realm of satellite hunting? A few weeks ago, a discussion popped up on Twitter for the possibility of spotting an elusive set of targets still in space. In early 1958, the United States orbited the Vanguard 1 spacecraft, the first of a series of three successful launches of Project Vanguard and only the second successful object placed in orbit by the United States following Explorer 1.

Two (count ‘em!) launches will light up the Florida Space Coast over the next few days; that of the Space Shuttle Endeavour on mission STS-130 and the Solar Dynamics Observatory (SDO). STS-130 is scheduled to liftoff from launch pad 39A out of the Kennedy Space Center on the morning of Sunday, February 7th at 04:39 AM EST enroute to the International Space Station. Cargo includes the Tranquility connecting node which houses the Cupola, a Millennium Falcon-like window that will give residents unprecedented views and aid in spacewalks and exterior work.

Pictured is a Delta IV rocket launch from Cape Canaveral on November 21st, 2010. The image is a 20 second exposure taken at dusk, shot from about 100 miles west of the launch site. The launch placed a classified payload in orbit for the United States Air Force.

Difficult but not impossible to catch against the dawn or dusk sky, spotting an extreme crescent moon can be a challenge. The slender crescent pictured was shot 30 minutes before sunrise when the Moon was less than 20 hours away from New. A true feat of visual athletics to catch, a good pair of binoculars or a well aimed wide field telescopic view can help with the hunt.

The Sun is our nearest star, and goes through an 11-year cycle of activity. This image was taken via a properly filtered telescope, and shows the Sun as it appeared during its last maximum peak in 2003. This was during solar cycle #23, a period during which the Sun hurled several large flares Earthward. The next solar cycle is due to peak around 2013-14.

Located in the belt of the constellation Orion, Messier 42, also known as the Orion Nebula is one of the finest deep sky objects in the northern hemisphere sky. Just visible as a faint smudge to the naked eye on a clear dark night, the Orion Nebula is a sure star party favorite, as it shows tendrils of gas contrasted with bright stars. M42 is a large stellar nursery, a star forming region about 1,000 light years distant.

Astronomical Observing Targets

Orbiting the planet in Low Earth Orbit (LEO) every 90 minutes, many people fail to realize that you can see the International Space Station (ISS) from most of the planet on a near-weekly basis. In fact, the ISS has been known to make up to four visible passes over the same location in one night. The image pictured is from the Fourth of July, 2011 and is a 20 second exposure of a bright ISS pass.

Next to the Sun, the two brightest objects in the sky are the Moon and the planet Venus. In fact, when Venus is favorably placed next to the Moon, it might just be possible to spot the two in the daytime. Another intriguing effect known as earthshine or ashen light is also seen in the image on the night side of the Moon; this is caused by sunlight reflected back off of the Earth towards our only satellite.
